. To all whom it may concern:

- Be it known that we, OTIS A. LUOE and Jornv C. NORMANRIOHARDS,'0itiZeI1S. of the United States, residin in Des Moines, county5 of Polk, and State of lowa, have invented a new and useful Improvementin Carriage- Shifts and Platen-Rotators, of which the fol-- lowing is aspecification.

, The object of our invention is to provide a means which, upon thepushing of a shift key, will cause t e carriage of a typewritingmachineto be rapidly conveyed to the starting position and to at thesame time turn the roller so that the paper will be in proper tlon toreceive the type for writing anew 'ne. A further obj ect 1s to providesuch a means n a simple, strong, durable and dpractically inex ensiveconstruction adapte cure to any of the standard makes of type-' writingmachines.

Another object is to rovide such a means which may be employe foroperating a series of machines from one motive power.

- Our invention consists of. certain details of construction hereinafterset forth, pointed out in our claims, and illustrated in theaccompanying drawings, in which Figure I showsaplan view of our attach-I ment Fig. II shows a sectional view taken on the line a-c, lookinginthe direction of the arrows bb; Fig. III shows a detail view-of one ofthe clamping members we employ;- Fig. IV shows a sectional view taken onthe line.a a, looking in the direction of the arrowsc-c; Fig. V shows aportion of a plan view of a Remington ty ewriter and'a ortion of our devce secured t ereto; Fig; V shows a side elevation view of the same; Fig.VII

shows .a portion of a plan view of a Smith vice secure thereto; Fig. IIIshows a side elevationview of the same ;.Fig. IX-shows a side elevation.viewof a belt wheel and drum we employ; Fi Xshows a transversesectional view of t e belt wheelwe employ; and Fig. XI shows adetailview of a pivotallymounted lever we employ. a

Referring to the accompanying drawings the reference numeral 10 is usedto indicate a latformprovidedwith a means 11 to secure it to the back ofa-typewriter and to this platform the-major portion of our device ismounted. The said platform is so constructed' that, when properlysecured to a machine, one lateral side thereof is in line with: itsrespective side of the writing'lma the writing machine, is a shaftPl-having its 'bearingsi'n standards 15 said shaft being parallelwiththe shaft'of' the motor 12, 'on which the belt wheel'13issecured,and on said shaftto be se- Premier t ewriter and a ortion of our de-/ onthe end .0

tending guide lever 27, formed by a rod robelt, and the lower extremityof the said lever chine and the other lateral side projects beyond itsrespective side of the machine. On

the rear of t e platform 10 is anchored amo tor ,12, rovided with a beltwheel 13 on'its forward ortion, 'and this motor is designed. to furnisall thepower by which our device is operated. Mounted near that end ofthe platform 10 which is in line with one side of 14'is mounted. a loosebelt wheel 16 and in close proximity thereto asecond belt wheel 17 whichis rigidly secured to a drum 18 both of which are loosely secured to thesaid shaft.

The said drum is provided with a chamber 19 in which aspring 2() issecured, which is designed to provide a tension and to take up slack ina cable 21' secured to the said drumas will be hereinafter explained.

The numeral 22 indicates a plate mounted on the shaft 14 and desig'nedtofit flush with the outer surface of the drum 18 and provide a coveringfor the chamber 19, and to said plate one end of the spring 20 issecured. The said plate is adjustable on the said shaft by means of aset screw 23, as shown, and it is obvious that theadjusting of thisplate on 35 the said shaft will loosen or tighten the tension of thespring 20;

Secured on" the platform 10, and in line with the division point betweenthe belt wheels 16 and 17, are two bearings-24 and 25, one beingimmediately in front of the saidbelt. wheels and theother being near theopposite end of the said platform, andjmounted in saidbearings'is alever 26 its centralfortion being bent outwardly and projects toward thewriting machine. Each end of said lever projects through its respectivebearing and the lever nearest the belt wheels 16 and 17 is mounted anupwardly exjecting upwardly to a point above the p ane .of the aforesaidbelt wheels and then curving back and its end projecting downwardly to apoint in line with the shaft 14, and within the two arms of the saidrod'the belt 28 connecting the belt wheel 13 and the belt wheels 16 and17, designed to travel. The space betw en'the two arms is designed to bemerely sficient to admit of the passage of the said is curved as shownat. 29; The-said lever in its normal position. is resting-in front ofthe2 j eeigave division betwenth jatat amt-17 5 belt stem-newl idlinhereinafter; explained, i

the deileve'rjs i the' eltfto, hes ed fromthe wheel 16 to, the wheel-17Secured to-thei other extremity of the lever- 26 is aforwardly-projecting lever 30,

1 tremity,-and the humeral31 indicates a lever, -inounted for radialmovement from its bearmg 32,]secured to the platform ,10 said lever is31 havins p miecting lug at its forward extremity, WhlO is designed toen- 'gagexthe under portion of the lever 30 and V provide a supporttherefor. The said lever 31 1 s provided with a tension spring,referably a {20co1l spring, which is secured in t e platform anddesigned to pull said lever toward and under the forward extremity ofthe .lever iwvhen the said lever is raised. The numeral 33 indicates aleaf spring secured to said plat- 25form its outer end engaging theforwardly curved portion of the lever 26 and designed to create apressure adaptedto push the for-- scale bar of the machine, said scalebar being mounted parallel with, and near the forward part of, theplatform 10, in bearings 35 and 36. The said scale bar is also, byconstruc tion, at right angles to the shaft 14. Mounted for longitudinalmovement on the bar 34 is a lug 37 provided with a set screw 37 and bythis means the lug is adjusted on the bar. Pivotally secured, for radialmovement, to the lug 37 is an arm 38 projecting upwardly to a pointslightly above the plane of the drum 18 and in the upper extremity ofsaid arm is an orifice 39 and through sald orifice .the cable secured tothe drum is threaded. By construction the arm 38 is in line with thedrum 18. v

Near the protruding end of the platform 10 and extending upwardlytherefrom are two standards 40 and 41 the forward standard 41 beingnearest the lateral edge of the platform,

and adj ustably secured to these standards, in

such a manner that its position may be raised or lowered thereon, is aforwardly projecting arm 42. This arm is composed of two or moretelescoping members which, obviously, makes it ca able of being extendedor short- 6 ened. At t e forward extremity of said 'arm anjoperation. l1 .q shown how ro ee'te forwardly causing f provided. with an elbowatits forward ex;

.is' secured-a pulley 43'and on the rear member of said arm, andin linewith the upwardly pigecting arm 38, is a second ulley 44.

he numeral 45 indicates a race rod se- .fcuredto the outer'member oftheextension armandfrom thence to the writing machine andidsigned as'a suport for the said arm.

;. Bybohstruction t e pulley on the outer .end ofthe extension arm isdesigned to be in line with, and slightly above the plane of, thespacing lever of the writing machine, providing said machine is ofastyle similar to the Smith Premier machine in common use and a cable,or small chain 21 is securedt'o the said spacing lever and then threadedthrough the pulleys 43 and 44 and the orifice 39 and wound around andsecured to the drum 18. A lug 47 is secured to the cable 21 at such apoint as will cause it to come in contact with the arm 38 when thecarriage of the machine has reached its limit of movement in its return.Projecting outwardly from the base of the lever 38 is an arm 48vprovided with an elbow 49 and in normal position said arm and elbow areresting on the surface of the platform 10, the elbow under the lever 26,but-when the u per portion of the lever 38 is forced toward I elbow onthe arm 48 is designed to come in contact with the under surface of thelever 26 and force itupwardly.

" The numeral 50 indicates a lug secured tothe platform 10 andprojecting over the lever 26 said lug being provided with a set screw 51located immediately over the central portion of the said'lever, asshown, and this is designed to serve as a buffer to determine the upwardlimit of movement of said lever.

The numeral 52 indicates a rod, its rear end secured in the lug on thelever 31, designed to extend forwardly to the front portion of themachine its outer end being at. tached to a shift key 53, secured to theframe of the typewriter, as shown, and a downward movement of the saidshift key is desi ned to cause said rod 52 to move forward ythus forcingthe supporting lug on the lever 31 'from'under the lever 30. From theconstruction of the parts, as described, it is obvious that the spring33 will then press the lever 26 downwardly and rotate, to a slightdegree, the ends of the said lever and it is equally obvious that thiswill change the position of the guide lever 27, with relation to thebelt wheels 16 and 17, and cause the belt to be shifted from the idler16 to the o erating wheel 17. As this wheel operates the drumthe drumthe '18 it is obvious that the drum will be rotated thusrolling up thecable 21 until-the lug 47 v comes in contact with, and moves, the arm 38which will cause the elbow 49 on the arm 48 to force the lever 26upwardly and obviously moves the guide lever 27 and shifts the belt tothe. idler 16. It is equally obvious that as said lever 26movesupwardly, as

'descfibed, the outer-end of the IeverBO I move upwardly and the lever31 actuated by f llJS lug engage theunder ortion of the lever 30, .Thepartsc of our pli hedthe ts spring again be forced backward and eviceare so i constructed that when the' carriage. of the. machine-hasreached-"it's limit of movement in the --retu rn. shift.- the cable.will" be.
